Hi all . I want ask you , in OnClick(NMHDR* pNMHDR, LRESULT* pResult) , how can I know which item is selected to retrieve tree item data ?
I try in follow way but I get always null :
void CMyViewTree::OnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
CTreeCtrl& Tree = GetTreeCtrl();
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
HTREEITEM hSelItem = pNMTreeView->itemNew.hItem;
if(hSelItem)TRACE("%d\n",Tree.GetItemData(hSelItem));
else TRACE("null\n");
*pResult = 0;
}
Thank you.

Like that :
void CMyListTree::OnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
CTreeCtrl& Tree = GetTreeCtrl();
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
HTREEITEM hItemSel = pNMTreeView->itemNew.hItem;
if(hItemSel)TRACE("%d\n",Tree.GetItemData(hItemSel));
else TRACE("null\n");
hItemSel = Tree.GetSelectedItem();
if(hItemSel)TRACE("%d\n",Tree.GetItemData(hItemSel));
else TRACE("null\n");
*pResult = 0;
}

You are doing the check in the wrong place, I think. You should capture the TVN_SELCHANGED notification as described here[^].
The best things in life are not things.

You should be handling TVN_SELCHANGED instead of NM_CLICK.

Hi!
I need to set Image to a CButton through code in MFC. I don't want to set through properties. I need to read the image path from an XML file and set it to the Button. How to set image through code? I also need to set Mouse Over image to a button. There is no Mouse Over event for Buttons. How to set the Mouse Over image in the same manner as above(reading the image path from an XML file and set it to the button).

Use ::LoadImage to load the image from the file as a bitmap.
Then use CBitmap::SetBitmap to set that as the bitmap for the button.
For the mouse over image, you need to set that in the WM_MOUSEMOVE message when the mouse is over the button.
In the WM_MOUSEMOVE handler, call TrackMouseEvent.
After this, WM_MOUSELEAVE message will be posted when the mouse leaves the area of the button.

I did my first website in pure HTML from a text editor... 
...and btw, MSHTML is an HTML library, not straight up HTML...

IHTMLDocument2::get_frame will give you an IHTMLFramesCollection2 interface.
Use IHTMLFramesCollection2::item to iterate through the collection.
Each iteration will give you an IHTMLElement interface corresponding to each frame.
Then use IHTMLElement::getAttribute to get the value of the SRC attribute.
|
|
|
|
|
_variant_t MSHTML::IHTMLFramesCollection2::item(VARIANT var); this is declaration of item function... there is no interface to get IHTMLElement...
|
|
|
|
|
The VARIANT will contain the IDispatch pointer of the frame element.
You can do a QueryInterface for an IHTMLElement on this IDispatch pointer.
|
|
|
|
|
for(long nfram = 0; nfram < pColFrames->length ; nfram ++)
{
_variant_t vIdx(i, VT_I4);
_variant_t vDisp;
vDisp = pColFrames->item(&vIdx);
if(vDisp.vt == VT_DISPATCH)
{
vDisp.pdispVal->QueryInterface(IID_IHTMLElement,(void**)&pElem);
...................//rest of operation
}
}
but always if(vDisp.vt == VT_DISPATCH) will fail...means vDisp.vt become empty.

Hi,

Can you suggest me expample or link to do so...
